Win98 Network Neighbour Error

[grendal]

I manage 65 pcs on my network. All users log onto a domain on a NT4 server (which contains a logon script). 3 win98 pc's logon onto the domain succesfully, but cannot be seen via NN (network neighbourhood). These machines have access to all domain services and can also see other users via NN. The workgroups for these machines currently exist, and all other settings appear to be in line with other win98 pc's. Anyone had a similar problem?

Cheers s-)
